Building the Foundations for Open Applied Earth System Science in ENVRI-FAIR

Ari Asmi, Daniela Franz, Andreas Petzold

The EU project ENVRI-FAIR builds on the Environmental Research Infrastructure (ENVRI) community that includes principal European producers and providers of environmental research data and research services. The ENVRI community integrates the four subdomains of the Earth system - Atmosphere, Ocean, Solid Earth, …

Carbon sink and CarbonSink+ : from observations to global potential

Tuomo Kalliokoski, Tuula Aalto, Jaana K. Bäck, Ekaterina V. Ezhova et autres

Carbon balance of forests is defined by three main processes; photosynthesis, autotrophic respiration, and heterotrophic respiration. Climate impact of forests include also non-carbon effects like albedo, biogenic aerosols, effect on clouds, evaporation and surface roughness. A well-thought measurement setup as well as …

ICOS eddy covariance flux-station site setup: a review

Corinna Rebmann, Marc Aubinet, HaPe Schmid, Nicola Arriga et autres

Abstract The Integrated Carbon Observation System Research Infrastructure aims to provide long-term, continuous observations of sources and sinks of greenhouse gases such as carbon dioxide, methane, nitrous oxide, and water vapour. At ICOS ecosystem stations, the principal technique for measurements of ecosystem-atmosphere …

Towards long-term standardised carbon and greenhouse gas observations for monitoring Europe’s terrestrial ecosystems: a review

Daniela Franz, Manuel Acosta, Núria Altimir, Nicola Arriga et autres

Abstract Research infrastructures play a key role in launching a new generation of integrated long-term, geographically distributed observation programmes designed to monitor climate change, better understand its impacts on global ecosystems, and evaluate possible mitigation and adaptation strategies. The pan-European Integrated Carbon …

Lake‐Atmosphere Heat Flux Dynamics of a Thermokarst Lake in Arctic Siberia

Daniela Franz, Ivan Mammarella, Julia Boike, Georgiy Kirillin et autres

Abstract We conducted eddy covariance measurements from April to August 2014 on a Siberian thermokarst lake. The study site is located in the Lena River Delta and characterized as a floating ice lake. Heat fluxes differed in magnitudes, directions and temporal patterns …

Exchange of CO2 and CH4 between a Siberian thaw lake and the atmosphere

Daniela Franz, Eric Larmanou, Niko Bornemann, Moritz Langer et autres

Freshwaters are an important component of the \ncontinental greenhouse gas (GHG) balance with emissions \nestimated to correspond to about 80 % of the \nland GHG sink [Bastviken et al., 2011]. Thaw lakes \nin permafrost landscapes and especially in Yedoma \npermafrost are considered …

Environmental controls of energy and trace gas exchanges at the water-air interface: Global synthesis of eddy fluxes over inland waters

Finite Infinity: Locating the Space of Circumstance

Daniela Franz

Islamic patterns are based on highly complex geometrical and numerical logics which introduce metaphysical rules or cycles into a physical world. The resultant geometry reveals a new set of characters, which, when subject to operations such as mirrored augmentation, rotational expansion, and …
